Character therapy trip

See item therapy on Jayes Blahg for an interesting idea for flushing out details and nuances of your main characters in a story or novel. Personally I found the idea intriguing and plan to give it a try in a story I’m currently working on.

Note, you don't have to actually use the therapy session in your story, but just to get a more intemate feel for the characters inner thoughts and motivations.
